Re: Help configuring LTE 4G on Cisco C887VAG-4G-GA-K9

bsgd · ‎09-18-2018

Hello all,

First of all let me tell you that Im am completely new to Cisco products and this is the first time I am trying to configure a Cisco product. I run an small business and have just bought a brand new LTE router.

I have the SIM card in and after accessing the default router address 10.10.10.1 I started the QUICK SETUP WIZARD. I just let everything set at default, but at the end, when I click the SUBMIT button, an error comes up saying: "Invalid input detected. Command: dialer string"

Below is the automatically generated CLI that I get when I click CLI PREVIEW.

I do have the knowledge to configure regular household routers, but this Cisco seems like a whole different beast, so I need some step by step help. All I want to do is get internet from my 4G provider, and thats all.

Thanks everyone and sorry if I am missing something obivous. I did try going into advance configuration mode and trying to check the 4G LTE interface as MAIN WAN INTERFACE but a message saying "APPLYING" pops up and never finishes, I have to close Chrome and restart all over.

Thanks!

I know this will sound stupid, but how do I get into command line and send this 'script' to the router?
I always configured routers using the web page and have no idea how to do this in a differene way, but would love to learn :)

Hello,

did you save what you configured with the 'wr mem' command ?

Cisco#wr mem

Can you post the output of:

Cisco#show run

bsgd · ‎09-19-2018

Sorry for the delay.

I did not use the wr mem command as I didnt know about it. I just hit end. I will try to hard reset the router and start all over again, this time using the wr mem command and will post back in a few minutes :)

Georg Pauwen · ‎09-20-2018

Let us know how it is going and if you need more help...

bsgd · ‎09-21-2018

First of all Georg, thank you very much for the quick reply and help.

After resetting and redoing the telnet steps and sending your suggested config, Im able to use the LTE data over ethernet, thank you very much.

I still have a few questions. First of all, on the web interface the router still says ther PRIMARY WAN INTERFACE is not configured, is this OK? Please see attached image.

Second, how do I configure another SIM CARD as backup interface (my router has 2 sim card slots) and how do I change the router interface and DHCP for a more 'commom' 192.168.0.1 range?

I tried reading and doing it myself but ended up loosing router access :(

I guess I need to study more how to 'program' these things...

Georg Pauwen · ‎09-21-2018

Configuring the second SIM card as a backup requires a few things. Can you post the running configuration as you have it now ?

bsgd · ‎09-21-2018

SHOW RUN returns quite a lt of stuff, here it goes:

Cisco#show run

-----------------------------------------------------------------------

Cisco Configuration Professional (Cisco CP) is installed on this device
and it provides the default username "cisco" for one-time use. If you have
already used the username "cisco" to login to the router and your IOS image
supports the "one-time" user option, then this username has already expired.
You will not be able to login to the router with this username after you exit
this session.

It is strongly suggested that you create a new username with a privilege level
of 15 using the following command.

username <myuser> privilege 15 secret 0 <mypassword>

Replace <myuser> and <mypassword> with the username and password you
want to use.

Hello,

I'll have a look...

Georg Pauwen · ‎09-21-2018

Hello,

your router has only 1 controller, so you can only configure failover, that is, both SIMs cannot be active at the same time.

When you issue the command:

show cellular 0 profile

you probably see 1 profile in there. You need to create a second one for the second SIM, e.g.:

Cisco#cellular 0/0/0 lte profile create 2 test.com <-- this needs to be what your ISP has provided

and attach it to slot 1 (slot 0 by default is the primary, slot 1 the backup):

Cisco# configure terminal
Cisco(config)# controller Cellular 0
Cisco(config-controller)# lte sim data-profile 2 attach-profile 2 slot 1

The EEM script below is optional, it will activate the backup SIM when the primary fails:

event manager applet SIM_FAILOVER
event snmp oid 1.3.6.1.4.1.9.9.661.1.3.2.1.4.14 get-type exact entry-op le entry-val "2" poll-interval 120
action 1.0 cli command "enable"
action 1.1 cli command "clear interface cellular 0"
action 1.2 cli command "cellular 0 gsm sim activate slot 1"
action 1.3 cli command "end"
action 1.4 cli command "clear ip route *"

bsgd · ‎09-21-2018

Cisco#cellular 0/0/0 lte profile create 2 test.com <-- this needs to be what your ISP has provided

What exactly is test.com? I dont know what to ask my ISP. I didnt configure this for SIM 0 either...

Thank you :)

Georg Pauwen · ‎09-22-2018

Hello,

do you have both SIM cards inserted ? If so, post the output of 'show cellular 0 profile'...
